Omg those screams are messy. The whole edit is. Why change something that didn't need changing? Ugh. I hope this version doesn't go out to UK stations.
The original is flawless, there's no need to change it ahhh.
It's not that I hate the idea of the radio edit, I just don't like the woman's voice and think it doesn't fit sonically. Maybe if it was Rita or even Katy doing that new stuff on the chorus... the outro is okay (and Rita's new ad lib too).
